Honeywell VGF21LS30 3-Inch Flanged Globe Valve 2-Way Linear Flow

The Honeywell VGF21LS30 is a professional-grade 3-inch flanged globe valve designed for commercial HVAC applications. This two-way valve features linear flow characteristics with a flow coefficient (Cv) of 125, making it ideal for precise modulating control in heating, ventilation, and air conditioning systems.

Key Features:

• ANSI Class 125 cast iron body with flanged end connections for easy installation
• Stainless steel trim and seat for long-lasting durability and corrosion resistance
• Linear flow characteristic with 0.75-inch stem travel for accurate positioning
• Suitable for chilled water/glycol solutions up to 50%, heating water, and steam up to 100 psig
• Maximum operating temperature of 353°F for steam applications
• ANSI Class III seat leakage (less than 0.05% of Cv) for reliable shut-off
• Self-adjusting packing minimizes maintenance requirements
• Face-to-face flange dimensions per ANSI/ISA S75.03 standard
• Stem-down-to-close operation for fail-safe performance
• Compatible with various electric and pneumatic actuators (actuator sold separately)

This valve is designed exclusively for closed-loop HVAC systems and is not suitable for open-loop applications such as condenser water or potable water systems. The VGF21LS30 provides precise temperature control and reliable performance in commercial building applications.
